          ACETO CORPORATION ANNOUNCES SECOND QUARTER FINANCIAL RESULTS

LAKE SUCCESS, NY - February 9, 2006 - Aceto Corporation (NASDAQ:ACET), a global
distributor of chemically-derived pharmaceuticals, biopharmaceuticals, specialty
chemicals and agrochemicals, today announced results of operations for its
fiscal 2006 second quarter and six months ended December 31, 2005.

Net sales for the second quarter were $69.5 million, compared to $76.7 million
in the second quarter of fiscal year 2005. This decline reflects the previously
disclosed decrease in sales of two active pharmaceutical ingredients (APIs) due
to intense competition. Sales of those two products in the second quarter of
fiscal year 2006 were $1.3 million, compared with $6.6 million in the second
quarter of fiscal year 2005, a decrease of $5.3 million. Additionally, the
Company's foreign subsidiaries, primarily its German and French operations,
experienced a $3.4 million decrease in Health Sciences sales due to a shift in
the demand pattern, as well as a modification of the French government's generic
drug reimbursement policy, that caused delays in shipments. The Company believes
it will recover a portion of these sales in future periods. Aceto's domestic API
sales increased $1.4 million during the second quarter of fiscal 2006 as
compared to the second quarter of last fiscal year.

Net income was $1.5 million or $0.06 per diluted share in the second quarter of
fiscal 2006 (which included a $0.01 per diluted share charge for exiting the
facility previously occupied by the Company's former Institutional Sanitary
Supplies segment) versus $2.0 million or $0.08 per diluted share in the same
quarter last year.

Net sales for the six months ended December 31, 2005 were $144.5 million
compared to $157.2 million in the same period of the prior year, due to the
aforementioned factors. Net income was $3.5 million or $0.14 per diluted share
in the first half of fiscal 2006, compared to $5.3 million or $0.22 per diluted
share in the same period of fiscal 2005.

Aceto closed the second quarter in a strong financial position, highlighted by
working capital of $97.4 million, no long-term debt, and shareholders' equity of
$108.8 million at December 31, 2005.

Leonard S. Schwartz, Chairman, CEO, and President of Aceto, stated, "Our results
for the quarter were slightly ahead of our expectations, due in part to our
successful efforts to cut SG&A expenses while maintaining full operational
capability and efficiency. Excluding the $0.38 million one-time charge for
exiting the Institutional Sanitary Supplies facility, SG&A was $9.3 million,
which was the lowest quarterly level in two years. We expect to further reduce
SG&A marginally in the coming quarters. While our core business is performing
reasonably well, particularly in light of the continuing competitive market
conditions in generic drugs, we are committed to expanding our business via our
Strategic Growth Initiatives, which are as follows:

o       Veterinary Vaccines - Our submissions to the USDA for a range of
        vaccines for companion animals are in the final stages of review. We
        anticipate approval in May/June of this year and expect to commence
        commercial sales immediately thereafter, as we have a definitive
        marketing plan in place and are in contact with prospective customers.
        These products will be sold under the Aceto label, which is a first for
        the Company.

o       Human Biopharmaceuticals - We are pleased that progress has been made
        recently in the EU towards approval of a major generic biopharmaceutical
        and hope it will influence US regulators and Congress to create a
        pathway for approval in the US. This is sorely needed to combat the
        continuing rise of health care costs, particularly in
        biopharmaceuticals. We would like to caution that there is no definitive
        time frame for approval in the U.S. However, if the approval in the U.S
        occurs, we are prepared to capitalize on Aceto's unique position, with a
        range of 38 products that we can bring to market.

o       Finished Dosage Forms - We previously disclosed that we were
        investigating selling finished dosage forms directly into distribution
        channels. We can now report that we have identified eight viable
        products to date for this initiative, for which we have a highly
        qualified, long-standing supplier of APIs who has moved downstream to
        dosage forms. We are working to expand the range of products that we can
        offer, aiming to increase it to 20 products. Our work in the marketplace
        is continuing and we believe that,



        given the viability of supply, of which we are quite confident, we will
        enter distribution channels with finished dosage forms, sold either
        under our label or private labels of our customers.

o       Chemicals and Colorants - We are very pleased that the Chinese chemical
        industry continues its rapid growth and we are investing resources in an
        effort to bring new Chinese products to the US and European chemical
        markets. Aceto's strengths in sourcing and supplying a wide range of
        products are unique, and our considerable operations in Shanghai support
        this activity.

o       Agrochemicals - We are on track to launch four new products before the
        end of calendar 2007, as we have previously disclosed."

Mr. Schwartz concluded, "In the third quarter of fiscal 2006, we expect to earn
approximately $0.08 per diluted share. We continue to be optimistic about
Aceto's long-term prospects and look forward to reporting on the Company's
developments."
